1.)The two circles have diameters of 1 000 mm and 500 mm. (Not to scale). 1.1 What is the scale factor of the small circle to the big circle? 1.2 What is the area factor of the big circle to the small circle? 2.) The two triangles are similar. (Not to scale.) The length of the base of the bigger triangle is 30 mm and that of the smaller triangle is 18 mm. The height of the bigger triangle is 20 mm. 2.1 Calculate the height of the smaller triangle. 2.2 Calculate the area of the bigger triangle. 2.3 Use the area factor to the area factor to find the area of the smaller triangle. 3.) The ratio of the area of two circles is 16:25. What is the ratio of their diameters? 3.2) What is the radius of the smaller circle if the larger circle has an area of 1 257 cm?
